长征八号的“专属座位”长啥样?记者实探……
Jin Rong Shi Bao· 2025-09-24 13:59
伴随着椰林海风,一枚枚火箭喷射出烈焰,像"钢铁侠"般直冲云霄,奔向星辰大海。这不是科幻大片, 而是海南商业航天发射场的真实写照。 走进海南商业航天发射场,站在一号发射工位的脚下,记者们仰望着这座"钢铁巨兽"纷纷发出感慨—— 它远比在电视中看到的场景更加高耸、更加震撼。 海南商业航天发射场一号发射工位是长征八号火箭的"专属座位"。今年8月26日,长征八号甲运载火箭 在这里顺利发射,成功将卫星互联网低轨10组卫星送入太空。作为我国唯一一个商业航天发射场,目 前,这里已具备了"双工位、多型号、高频次"的发射能力。 "一号工位的塔高是90米,最顶上的橙色装置就是塔吊,起吊重量可以达到55吨,最底下是发射台,对 火箭提供重要的支撑作用。"海南商业航天发射场一号发射工位首席指挥张小军为记者们详细"解剖"了 火箭的"工位"。 在他看来,最值得一提的还是发射台底部的导流装置。"一号发射工位首次采用了地面导流装置,导流 锥从两侧对燃气进行排导喷水,实现了降温降噪。"张小军介绍称,一号工位的四周还设有四个避雷 塔,塔高120米,主要是为海南雷暴等极端天气做准备。 近年来,随着商业卫星广泛应用,商业航天的业务量迅速增长。然而,与商 ...
“十四五”期间全国统一大市场的“四梁八柱”基本建立
Yang Shi Xin Wen· 2025-09-20 16:13
当今世界经济,最宝贵的资源之一是市场,而中国超大规模且极具增长潜力的市场,是我国经济发展的巨大优势。"十四五"时期,面对纷繁复杂的外部环 境,中国经济顶住压力迎难而上,展现了强大的韧性,其中市场的建设发挥了关键作用。五年来,中国的营商环境越来越好,全国统一大市场的"四梁八 柱"基本建立起来,成为中国经济高质量发展的压舱石。 2025年,国家发布的最新版《市场准入负面清单》进一步缩减了商业航天领域的市场准入限制,这也吸引了更多像星际荣耀这样的民营企业加入这条前景广 阔的新赛道。截至今年上半年,已经有超过700家航天相关企业入驻文昌航天城,涵盖了火箭链、卫星链、数据链等八个方向。我国在商业航天领域持续放 开准入门槛、不断优化营商环境,正是他们的信心来源。 商业航天领域是我国市场准入逐步放开的一个缩影。党的十八大以来,我国逐步建立全国统一的市场准入负面清单制度。历经4次修订,清单数量从2018年 版的151项压减到2025年版的106项,压缩比例约30%。准入的放开也体现在实打实的数据上,"十四五"以来,我国企业净增1999.9万户,个体工商户净增 3394.6万户。 今年8月26日凌晨,长征八号甲运载火箭在海南文 ...
